spent some time trying to get it working. checken the fusebox but there is no relais in that position, fitted one and put the lowbeams on. tried the 3 unmarked switches in the top part of the dashboard cluster but no voltage on the 2 leads. pulled the switches to check if the colorcoding on the wires corresponds with the schematics. No switch has the 2x yellow 1x grey wiring. pulled the top part of the radiocluster to check if the connector had fallen down or was never routed right, did not find it. I will try the bottom part behind the gearlever tomorrow, maybe it is situated behind there. Otherwise will have to pull new wiring for the foglight :'(.
Did make some stainless brackets and mounted them up to the car,

Love the look, fills in the empty part under the bumper just right.
